An RAF helicopter pilot known on our squadron for his terribly unfortunate stutter went on a army exchange tour (on Lynx, IIRC).
The army thoughtfully (!) gave him the callsign "Four Four Foxtrot" and made him lead formations on landaways.
"F..F...F....F.....FFFFFFFEr....FFFFFFFFEr........ .FFFFFFFEr.......
Whilst at "Gut" they gave him "44"!
Can remember him landing a very early computer flt sim with the stick cross-wired with the left/rights - he was the only one to do this, "clever" I thought!
Went on to be a helicopter TP.
(Also crashed an airship!)
Highlighted a lateral CofG problem on the MD900 during the trials for DHFS, months before the makers came clean!
Where are you now, "Herr Schlanger"??
